Thanks. That's very helpful.
As you pointed out, I can see that most of the problem comes from the slicing software path planning.
In addition to getting it to print each island completely, it would be great if we could control the start point(s). I could live with some of the irregularities if I had control over where they appear on the part.
For example, if I could specify that the path start at the back of the part, then the irregularities would end up on a non-critical side of the part. For functional parts it isn't a big concern, but for aesthetic designs it becomes an important issue.
